Zoophilia, a sexual fetish also known as "bestiality," is the practice of having sex with an animal.
Most zoophiles experience the first stirrings of their fetish between the ages of 11 and 14.
The act of bonifering an animal may be older than recorded history, because it's been depicted in cave paintings
from Val Comonica, circa 8000 BC.

The Kinsey reports rated the percentage of people who had sexual interaction with animals at some point in their lives as 8% for men and
3.6% for women. A 1982 study suggested that 7.5 percent of 186 university students had interacted sexually with an animal.
Sexual fantasies about zoophilic acts can occur in people who do not have any wish to experience them in real life.
